Please retain the shipping cartons in case subsequent shipping of the product becomes necessary. Product Description The P MX 3312/3313 D is a high quality analog Audio multiplexer (Audio Embedder) designed primarily for broadcast and professional applications. The Module accepts 2 external analog Audio Stereo inputs (combined into one audio group) and multiplexes this into the incoming SDI video input. Group insertion is selectable (1 through 4). Four separate SDI outputs of the video, with embedded audio are provided. Existing audio groups can be overwritten, deleted or passed transparently. Four separate SDI outputs of the embedded signal is provided which could be used to cascade several modules for additional audio group insertion. The Module uses Sub D connections for audio and standard 75-Ohm (BNC) interconnections for video. The P MX 3312/3313 has a variety of features, which include: User selectable audio groups. (1 4) 525 and 625 line standard. (auto detect) Supports 4:3 / 16:9 aspect ratios. 270 and 360Mbits/s (auto detect) Supports 20 and 24 bit audio. Page 7
Supports 8 and 10 bit video. EDH insertion back into outgoing SDI data streams. Video to green if SDI input lost. No audio insertion if audio input lost. local DIP switches and LED's for control and status monitoring. Microprocessor controlled. Remote control interface. All settings stored in non-volatile flash ram. The module has a built in micro-controller with local controls, status and alarm indicators and well as internal flash ram for storing setups. Any operational parameters configured and stored into the module are recalled when powered up. The P MX 3312/3313 D is part of the 3000 series of MiniModules, which offer high quality, modularity and flexibility in a very small form factor ideal for applications where space is at a premium.

Installation Mechanical Stand Alone Operation The P MX 3312/3313 D MiniModule can be used in a stand alone application. There are two options for the use of the module in this way. a) Using the R FR 3005 Rack Frame 1 option. This allows up to any 10 of the MiniModules to be secured onto a rack frame assembly for 19 inch rack mounting. This keeps the modules secured, organized and out of the way. The R PS 3001 power brick option or the R FR 3010 option is required to power each module. Please refer to the R FR 3005 Reference Manual supplied with this option for more details. b) Single Use. The MiniModule can be powered independently with the R PS 3001 option and used in any location where this functionality is required.! Caution. Care needs to be taken when using the module in this way, as it is not physically secured. Keep the module away from the floor to avoid the risk of someone stepping or tripping on the unit, and locate the unit away from excessive sources of heat and any sources or moisture. If using more than one MiniModule in any installation, the R FR 3005/3010 Rack frame combination is highly recommended. Page 13
Multiple Units Most applications will require more than one MiniModule, which can include any of the available Series 3000 MiniModule product range. There are two options for mounting multiple units. a) Using the R FR 3005 Rack Frame option. This allows up to any 10 of the MiniModules to be secured onto a rack frame assembly for 19 inch rack mounting. The R PS 3001 power brick option or the R FR 3010 option is required to power each module. Please refer to the R FR 3005 Reference Manual for more details. b) Using the R FR 3010 Rack frame extension option. Can be combined with the R FR 3005 Rack frame option. Each module plugs into a connection bus, which provides common power for all modules. (no R PS external power supplies are needed). The very small size and density of the MiniModules combined with the available rack frame options allows the addition of a complex and custom signal distribution system without taking any additional front rack space. The rack frames are designed for installation in the back of 19-inch racks where there is normally plenty of available space. Ideal for mobile truck installations and facility expansions where space is at a premium. Page 14
Electrical Installation Stand Alone Operation The MiniModule requires the R PS 3001 power brick option for stand-alone operation. Three versions are available: R PS 3001 E for European markets, R PS 3001 U for the US markets and the R PS 3001-3 desk power supply. Please ensure you have the correct power option for your region. The connection to the module is made with a small 5-pin connector, which has a twist bayonet securing system. Please make sure the connection is solid and locked in place. A strain relief is included within the module to prevent excessive strain on the connection. Signal connections should be made with care, please ensure connections are correct and compatible equipment is feeding / receiving the signals from the module or damage can result.!! Caution. Only use the optional LYNX R PS 3001 power modules. Ensure the 5-pin power connector is locked securely in place. Caution. Care needs to be taken when using the module in this way, if it is not physically secured. Keep the module away from the floor to avoid the risk of someone stepping or tripping on the unit, and locate the unit away from excessive sources of heat and any sources or moisture. Page 15
Multiple Units When installing multiple MiniModule units it is recommended you use the R FR 3005 Rack Frame 1 and / or R FR 3010 Rack Frame 2 options. Please refer to the documentation supplied with these options for details on electrical installation. Page 16
Settings and Control The P MX 3312/3313 is configured via 3 integrated dip switches (SW1, SW2 and SW3) (Figure 2) Switch Settings Below are the switch settings for the two 4-position dip-switches (SW2 and SW3) are defined. Please see the section following the table for more detail on each switch function. SW 1 Position Set Function ON Select FS 18dBu (EU P MX 3312 D) 1 Select FS 24dBu (US P MX 3313 D) OFF Select Low FS range (12dBu or 15dBu) (EU) Select Low FS range (15dBu or 18dBu) (US) ON FS range = 15dBu (EU) 2 FS range = 18dBu (US) OFF FS range = 12dBu (EU) FS range = 15dBu (US) 3 ON Mute channel 1 OFF Normal operation 4 ON Mute channel 2 OFF Normal operation SW 2 Position Set Function 1 ON Local Adjustment Enabled OFF Local Adjustment Disabled 2 ON 24 bit AES output OFF 20 bit AES output 3 ON Delete ALL incoming embedded AES audio OFF ONLY replace Audio group selected with SW2 SW 3 Position Set Function 1 ON Audio Group 1 selected OFF 2 ON Audio Group 2 selected OFF 3 ON Audio Group 3 selected OFF 4 ON Audio Group 4 selected OFF Page 17
Switch Function Detail All settings are stored in Flash Ram inside the module (see Auto Store section in this manual). Settings will be recalled on power up. SW 1: Dip Switch 1. Full Scale (FS) range select. This switch is used to select either high or low FS range presets ON selects the high range, which means 18dBu (P MX 3312) or 24dBu (P MX 3313) OFF selects the low range 12dBu or 15dBu (P MX 3312) or 15dBu or 18dBu (P MX 3313) (depending on the selection of switch 2) Dip Switch 2. Select full scale range (Switch 1 OFF) ON =15dBu for P MX 3312 and 18dBu for P MX 3313 OFF =12dBu for P MX 3312 and 15dBu for P MX 3313 Note. Switch 1 and switch 2 are interactive Dip Switch 3. Mute channel 1. Selecting ON will mute the audio on channel 1 OFF is normal operation Dip Switch 4. Mute channel 2. Selecting ON will mute the audio on channel 2 OFF is normal operation Page 18
SW 2 Dip Switch 1 This switch enables local control using the dipswitches. ON enables local control and makes selections on the dipswitch active, and OFF disables local control (locking out any local changes) Note. When Switch 1 is initially switched to ON, the static settings currently set on the dip-switches may not reflect the actual configuration stored in the module. This is because all settings can be changed from the remote control system or via the Service Adapter. This overrides the local dip switches regardless of Switch 1 ON/OFF setting. To ensure the module reads the local dip switch settings it is recommended to toggle Switch 1 ON- OFF-ON before making any local changes to the dip switches. SW2 Dip Switch 2 20 / 24 bit operation. When set to ON the AES audio output will be 24 bits wide (which is normal). When set to OFF the AES audio output can be set to 20 bits, which is sometimes necessary for downstream equipment which may not be compatible with 24 bits operation. Page 19
SW2 Dip Switch 3 Delete embedded audio. When set to ON this will delete ALL incoming AES audio signals on the input SDI signal (if any). When set to OFF only the channels selected for embedding (using SW2) will be overwritten. Any remaining audio, which was present on the incoming SDI signal will pass transparently. SW 2 Dip Switch 4 No function here SW3 Dip Switch 1 through 4 Select Audio Groups. These four switches are used to select which audio groups are to be embedded into the incoming SDI video. ON selects the audio group and OFF deselects it. Auto Store If no parameters are changed for 10 seconds then the current settings will be written into flash memory automatically, this can be seen by the front LED flashing yellow four times. Page 20
